Hi Peter,
Thanks for taking the time to look at this.
I see now that Adobe have updated the RH 2015 Help page replacing IE9 with IE10 in the Responsive HTML5 Layout - Supported Browsers section. Looking at the original RH 2015 Help text, it looks like they simply copied the Multiscreen Layout section and relabeled it as Responsive HTML5.
I have tested the sample project with Chrome and Firefox and found the same four issues are happening in both browsers. I am using Firefox 46.0.1 and Chrome 50.0.2661.94, which I believe are the latest versions. I do not have Edge and only IE9. However, other projects that I have where the Master project includes topics, the links will work correctly but the index and search only contain topics from the Master project. This can sometimes be fixed by republishing the Master project. At this time it all seems very inconsistent.
Cheers,
Chris

I am sorry it has taken me so long to look in more detail but the good news is that the project you sent me is now working fine in both Firefox and IE.
The problem was the setup. You need to generate the parent to one folder which will then create folders ready for the child projects. Then you must generate each child to the child folder within the mergedProjects folder within the parent folder. You were generating to the !SSL! folder of each project.
Let me know if you want me to send the working version back to you.
